UniTak3D Ender 3 V2 Y-axis Belt Tensioner Upgrade for Creality Ender 3 V2 Ender 3 Pro CR10 Mega Zero 2.0 Flashforge-Aquila AURORA-A5X 3D Printer 2040 Profile

I have 3 Standard Ender3s and this is a much needed upgrade. The price is low enough I am not sure why anyone wouldnt pick this up. It does not come with wrenches but the kit you got with your printer has everything you need. Once I found the sizes I need I uninstalled previous tension-er and had this upgrade installed in a little under 3 minutes for each of the 3 printers. All metal design gives a good quality feel. The knob lets me decide how tight I need to belt to be.

The description says it fits the Neptune 2. This absolutely will not fit the Elegoo Neptune 2. It does not even come close to fitting the rails. If you are buying this for the Elegoo Neptune 2 don’t, it won’t fit.

Simple to install and works great to keep the right amount of tension on my Ender 3.

Replaced a printed (PLA) tensioner on my CR-10 mini that came apart after a year or two of wear and tear. While I like printing mods in general, this is just more solid, easy to adjust and fits the rail and belt perfectly. The old printed mod was a little off and had some wiggle that led to some annoying belt rubbing from time to time.

Works well - easy install

I had a belt starting to sag a bit so I decided to pick one of these up and its went right one easy and has made keeping the belts tight SOOO much easier.

Product really well made! It fits right!! Better than the stock one!!! Highly recommend!!!

The toothed idlers wheels wobbled from the time it was opened. Everything else about this tensioner would be great if the idler was good.

It was a breeze to install and made tightening the x belt super easy. 10/10 would recommend.

This is the second one that I have purchased. Work great and you can adjust on the fly. When installing you can take the item apart and install it without messing with the belts. Happy!!! Thanks
